I go to the silver lake dunes in Mears, MI a few times a year but have never taken my griz. I was wondering if anyone has ever run real paddle tires and what the outcome was. I have found scat trak paddles in 23.5x8x12, 23.5x10x12 and 26x8x12, and 26x10x12 sizes in various paddle numbers and heights. I just don't know where to begin in selecting the correct tire. I currently run a stock griz with swamplite tires in stock sizes. I think they will dig too much and not propel the quad forward enough. With the paddle I believe it will float on top of the sand better and get plenty of traction. Which height is better? The 23's will accelerate faster but run out of top speed and how will the clutch act? With the 26's, it won't accelerate as quickly, but will achieve a faster top speed which is desirable in the dunes? When I rode my GF's Eiger 400 in the dunes, it would make it to the top, but would be bogging severly, and using four wheel drive didn't make any difference. I assume the Grizzly has enough balls to pull hard up the big dunes, but will the difference be in the paddles or not? I'm a big guy at 6'4" and 275lbs. and I don't want to have to purchase paddles twice. I also assume I would run paddles up front or would that be too much traction? I am also in dire need of some 12" bead lock or reinforced ring aluminum wheels, much like on the sport quads. I don't really care for the cast aluminum wheels out right now for utility quads. I found some OMF 12" beadlocks but at $179 per wheel, it's kind of pricy! I like the ITP t-9 baja wheels, but no 12"
